GeneDx RCV000657474 SCV000779209 pathogenic not provided 2018-02-19 criteria provided, single submitter clinical testing This duplication of one nucleotide in PTCH1 is denoted c.2712dupA at the cDNA level and p.Gln905ThrfsX11 (Q905TfsX11) at the protein level. The normal sequence, with the base that is duplicated in brackets, is CTAA[dupA]CAGC. The duplication causes a frameshift which changes a Glutamine to a Threonine at codon 905, and creates a premature stop codon at position 11 of the new reading frame. This variant is predicted to cause loss of normal protein function through either protein truncation or nonsense-mediated mRNA decay. Also reported as PTCH1 c.2712_2713insA using alternate nomenclature, this variant has been observed in at least one family with Nevoid basal cell carcinoma syndrome (Fuji 2011, Guo 2013). We consider this variant to be pathogenic.
